"We confirm that East Jerusalem is an inseparable part of the Palestinian land," Saudi King Salman said.

The status of Jerusalem, which is home to holy religious sites and has particular significance for Muslims, Christians and Jews, has long remained a sensitive topic and one of the core issues in the Israel-Palestine conflict.

"Washington says it has taken the Jerusalem file off the negotiation table," said Palestinian President Mahmoud Abbas.

"This violates international law and is a precedent that we consider a major setback."

Qatar blockade not discussed

The summit was the first since a major diplomatic dispute between Qatar and some its Gulf neighbours.

Saudi Arabia, the UAE, Bahrain - all members of the Gulf Cooperation Council (GCC) - and Egypt cut diplomatic ties with Doha on June 5, 2017, and imposed a land, sea and air embargo, accusing it of supporting "terrorism". Qatar has repeatedly denied the allegations.

Al-Jubeir, Saudi foreign minister, said Qatar was not on the agenda because "it's not a big issue".

"It's not a big problem," he said. "It's a very, very small problem."

While Qatar's emir did not attend the summit, the country's Arab League representative was present at the meeting.
